In my opinion:

Why do I need to overclock my own machine?

a) I risk overheating the chip.

b) The ventilation is not conducive of excessive heat. (It's a PDA not a PC.)

c) If you put the wrong setting you could
i) irreverisbly damage the software/ROM
ii) you may very well void your warranty

For those of us that didn't study EE in college, there's no hope.

Excuse my tirade, but you need 3rd party crutches to make the Axim move as it should.

I like it cause it's kinda like playing Russian Roulette

Stepping Through Life...

Yes, there is some talk about overclocking going on, but the discussion was/is really centered around trying to clock the CPU at the rate it is designed to run at, setting the PXBus to 200. (Where MobilePC 2003 will LET you set it, but PocketPc 2002 will not)

For that matter... Dell intentionally turns down the CPU multipliers on the Basic model to help justify the price of the Advanced model. If the PXA255 processor running at 400Mhz doesn't overheat an X5 Advanced.. it ain't gonna overheat a Basic.

overclocking the ram is dangerous, risk of losing data. mine locked up but when testing at 597mhz thankfully everything is stil there 472mhz isnt that risky with cpuscalar

I don't know about 476 (300 might be acceptable) but at the very least how do I get my ax up to 200

Disclaimer I am an IT guy NOT an EE, is there a nice simple (dare I dream free) way to do this?

Aximluvah:

I think they are referring to running the Clock Speed at 476MHz (as opposed to the factory 400MHz on the Axim Advanced). They are not overclocking the Bus Speed to 476MHz, just 200MHz.

how much extra battery life does overclocking take? noticeable?

2x SimpleTech Bonzai USB2 mini-drive/SD card reader
2x Lexar 1GB (Non-Hi Speed!) SD (USA): write speed = 5.5MB/sec (37.5X) Space avail. (formatted) = 975MB
1x SimpleTech 512MB SD (Taiwan?): write speed = 5.3MB/sec (36.4X)...... Space avail. (formatted) = 489MB
RMA'd: SimpleTech 512MB SD (Japan): write speed = 3.9MB/sec (26.6X)... Space avail. (formatted) = 491MB
Sold: Viking 256MB SD (Taiwan): write speed = 1.5MB/sec (10.2X)........... Space avail. (formatted) = 241MB
Sold: Viking 128MB SD (Japan): write speed = 1.5MB/sec (10.2X)............. Space avail. (formatted) = 120MB

The thing is that when I have to sync important information with my PC, or it's crucial that I get something done at an instant, I can't afford "lockups" and "soft resets". I can't put down $250 on a PDA just because it's nice to look at. There needs to be a resonable level of reliability.

Nobody likes putting in an important phone number, appointment, or file and having it crash and erase your other important data.

I don't think that Dell lowered the multiplier on the processor speed "because of price." It doesn't make sense. Why offer a very capable processor, no matter what you step it down to, along with an Axim for cheap? I think the other stuff on the circuit board is cheap. The chipset, firmware, or whatever else was good enough for 2002 but not 2003.

Starforce

I'm not sure if the lowered bus speed is a "mess up", or if it is how Dell wanted it. But just keep in mind that this is Dell's first PDA, so simple mistakes could possibly happen in the design/production process. Other manufacturer's have had 20 or more models prior to their current ones.

I think you misunderstood what I said.

As you know, the Axim is offered in two models, the Basic (running at 300Mhz) and the Advanced (running at 400Mhz). However, both models run the exact same processor. The only difference is the speed they initialize the processor to.

For buying the Advanced... you get double the ram, 50% more ROM, a cradle, and 100 extra MHz.

I personally feel it's cheesy that I have to install a third party software to get it to operate at 100%. I wish there was a registry hack option for those of us running the pxa255 chip.

Advanced/PXA255(2k3 upg)
SD: 256Mb(Lexar) CF: 256Mb 12x(Lexar), 256Mb(Simpletech), 256Mb(Kingston)
DLink DCF-660W Wifi / DLink Wireless Router(DI-764)
Bibles for America(FREE)

What is the software that you are all using to overclock with? and is it free. If it is not do you know of any free software that will overclock the axim?

I'm using TurboTray (freeware) to take my 400Mhz to 498 Mhz. I've seen no ill effects. By the way, this same software will drop it down to 100 Mhz if I want to conserve battery life if I am only reading e-books. It works simply by toggling the icon in the system tray.

edbro,

do you have a link? google comes up with nothing.

I tried one.. I forgot the name but I only OC'd the CPU. Which apps OC the BUS?
